Control radiográfico de trasplante dentario: reporte de caso
Radiographic control of dental transplantation: a case report

El trasplante dentario es una opción terapéutica para reemplazar un órgano dental perdido, causado por un proceso carioso extenso, agenesia, trauma-tismos o iatrogenias. Este procedimiento quirúrgico traslada un órgano dental íntegro desde un alveolo donante hacia su lecho receptor; p...

Tiempo empleado para estimar edad dental en niños peruanos comparando el método de Demirjian y el cuadro integral del enfoque de Demirjian: un estudio piloto

Int. j. morphol; 41 (2), 2023
El objetivo de este estudio fue comparar el tiempo empleado al estimar la edad dental (ED) entre el método propuesto por Demirjian et al. y el cuadro integral del enfoque de Demirjian (DAEcc) utilizando radiografías panorámicas digitales de individuos peruanos de 5 a 13 años residentes en Lima. Se re...

Panoramic radiography and cone-beam computed tomography to measure distances between root apexes and anatomical structures

J. oral res. (Impresa); 11 (5), 2022
Aim: To compare the accuracy of the panoramic radiography with cone-beam computed tomography (CBCT) scans in measuring the distances between root apexes and the adjacent anatomical structures including the maxillary sinus and the mandibular canal. Material and Methods: A total of 200 CBCT scans (100 maxi...

Tooth and pulp chamber automatic segmentation with artificial intelligence network and morphometry method in cone-beam CT

Int. j. morphol; 40 (2), 2022
SUMMARY: This study aims to extract teeth and alveolar bone structures in CBCT images automatically, which is a key step in CBCT image analysis in the field of stomatology. In this study, semantic segmentation was used for automatic segmentation. Five marked classes of CBCT images were input for U-net ne...

Concordancia en la evaluación de tratamientos de endodoncia preclínica: un estudio en diferentes unidades académicas
Agreement in the evaluation of preclinical endodontic treatments: a study at different academic units

Objetivo: El objetivo del presente estudio fue analizar el grado de concordancia entre alumnos y docentes de dife- rentes unidades académicas en la evaluación radiográfica de tratamientos endodónticos realizados en dientes humanos “ex vivo”. Materiales y métodos: Un docente y un alu...

Accuracy of cone-beam CT in detecting vertical root fractures in teeth with post-endodontic restorations: an in vitro study

Acta sci., Health sci; 43 (), 2021
The aim of this study was to evaluate the accuracy of cone-beam CT (CBCT) for the detection of artificially created vertical root fractures (VRF) in extracted teeth restored with metallic (MP) and fiberglass (FGP) posts. After root canal obturation, 60 extracted human premolars were scanned...

Research on a segmentation and evaluation method combining tooth morphology features

Int. j. morphol; 38 (5), 2020
SUMMARY: To explore a new semi-automatic method to segment the teeth from the three-dimensional volume data which acquired from cone beam computed tomography (CBCT) scanner. Scanned dental cast models are used to evaluate the segmentation accuracy. The CBCT data are loaded to ORS software. Based on gray ...

Micro-computed tomographic analysis of apical foramen enlargement of mature teeth: a cadaveric study

Revitalization procedures have been extensively studied during the last decade and offers several advantages over root canal treatment, such as the recovery of the natural immune system. Mature teeth have a small apical foramen diameter (AFD), which could impair the ingrowth of tissue into the root canal...

Estimación de edad mediante la relación área pulpa/diente en caninos mandibulares: estudio en una muestra chilena utilizando el Método de Cameriere

Int. j. morphol; 38 (2), 2020
La estimación de edad compone un aspecto importante en investigaciones forenses. Diferentes métodos se han descrito en odontología forense basadas en la correlación entre la edad y estructuras dentales. Cameriere et al. proponen un método cuantitativo para estimación de edad en adultos, a partir de...

CBCT assessment of bone thickness in maxillary and mandibular teeth: an anatomic study

J. appl. oral sci; 28 (), 2020
Abstract The site of the sinus tract depends on the rate of resistance against abscess exudate drainage, bone morphology, and distance from the root apex to the outer cortical bone. Objective To assess apical bone thickness in buccal and palatal/lingual aspects of maxillary and mandibular teeth, using ...
